Oxygen for the cockpit crew
 

Hello everybody

In my company's new SOP there is a change about tha use of oxygen for cockpit crew: the cabin altitude must be 13,000 ft for the use of oxygen mask.

Something has been chenged in the regulation?

Thanks

It would be helpful if you mentioned under what regulations you're operating...

The first symptom of hypoxia is the loss of colour vision by night above 10000 feet. That is why pilots need oxygen above 10000msl.

I would be very surprised if any regulator allowed 13000 feet for pilots.

Be very surprised then! In the USA under part 91 regs, you a re allowed up to 14 000' for no more than 30 minutes at a time!

Who's going to change the warning systems to take this change into account?
